-
- LSD also has effects on 5-HT1C receptors, and its not entirely sure what the
- specific receptor mechanism is -- there's also the question of why the
- psychological effects seem to last much longer than the presence of the LSD
- molecule. One thing that is fairly sure is that LSD shuts down the firing of
- the seratonin neurons in the raphe, though.

-
- The impression that I've got is that this is probably applicable to all
- neurotransmitters -- they are predominantly either
- inhibitory or excitory, but not in all cases.

- Actually, a better explanation is the increased firing of the locus coereleus
- by its disinhibition due to the neurons in the raphe slowing down (since you
- are inhibiting an inhibitory neuron the result is excitation...). The l.c.
- has been associated with being a "sensory highway" in the brain, and has also
- been associated with feelings of anxiety, and theorized that its invovled
- with depression. My guess is that the hallucinations and stimulatory effects
- of LSD come from potentiating the l.c., while the effect on the 5-HT neurons
- in the raphe is responsible for its entheogenic effect on the mind.

-
- Yup, you've only had *psychedelic* experiences. To have a *hallucinogenic*
- experience you're supposed to take Ketamine (so I've read).

-
- I typically do not feel calmness, peace, empowerment, euphoria or anything like
- that. Its typically a dissasociative feeling (although I don't think thats
- a very good word for it), and I always feel like I'm walking along a "wall"
- that, if I'm not careful, I'll fall off of. Its useful for insight and
- seeing things from a different perspective, but its something I've got to
- be damn careful with.
-
- I believe this is a biochemical difference in the way LSD effects my
- mind, however... most people seem to get some kind of euphoric feeling or
- mild amphetamine-like stimulation that i don't get...
